Impact of preoperative ultrasonography findings on the patency rate of vascular access in Japanese hemodialysis patients

摘要

BackgroundAlthough ultrasonography before a vascular access (VA) operation has become popular in recent years, benchmarks for the diameter or blood flow of arteries or veins are not defined in Japan. The objective of the present study is to analyze the relationship between preoperative US findings and the patency rate of VA in Japanese hemodialysis patients.
